CN202636690U - Central spindle of oven with on-top heat source - Google Patents

Abstract

The utility model relates to a central spindle of an oven with an on-top heat source. A heat source of an existing oven is placed under a gridiron. A central spindle which can support a heat source with a swing arm to swing and control on-off of the heat source does not exist at present. The central spindle of the oven with the on-top heat source comprises a spindle body which is in a column shape. A guide groove loop, a limiting groove loop and a trigger groove are arranged on the outer wall of the spindle body in parallel. The central spindle is arranged at one end of the swing arm in inserted mode, and the swing arm swings around the central spindle to achieve movement of the heat source. The guide groove loop is arranged to be matched with a guide bulge loop in the swing arm so as to achieve smooth rotation of the swing arm. The limiting groove loop plays roles of limiting excessive swinging of the swing arm and controlling the on-off of the heat source through the trigger groove and by means of matching with a corresponding travel switch. The central spindle not only brings convenience to a user for taking and placing food, but also enables the heat source away from an operating position to be turned off automatically so that use safety of the heat source is ensured.

Description

A kind of axle core of thermal source overhead baking oven

Technical field

The utility model relates to a kind of baking oven equipment, is specifically related to a kind of axle core of thermal source overhead baking oven.

Background technology

Existing baking oven generally includes pedestal, be placed in the grill on the pedestal and be fixed on thermal source between grill and pedestal by connector, and the food that utilizes the heat that upwards distributes will be placed on the grill is baked.There is following defective in this organization plan: because thermal source and grill are interconnective fixed structure, in order to improve heat transfer efficiency, can try one's best near the bottom surface of grill in the installation site of thermal source, because regulating, thermal source has hysteresis quality, after being baked, food closes thermal source, heat remaining on the thermal source can continue to distribute and act on the food, and food is easily burned; In addition, thermal source is positioned at grill below, and the heat that thermal source distributes will see through grill and act on the bottom surface of food, and the operator is difficult to the end face judgement cooking level from food, and is easily excessive because observing the untimely food barbecuing that causes, and affects taste.So the inventor has invented a kind of baking oven of thermal source overhead, thermal source is erected at the top of grill by swing arm structure, the thermal source of overhead can affect the user and pick and place food, thermal source need to be rocked to a side and guarantee thermal source autoshutdown when moving apart its safe radiation areas, the thermal source that there is no at present the swing arm of a kind of energy support belt swings and controls the axle core of its switch.

The utility model content

In order to solve the deficiencies in the prior art, the utility model provides a kind of can support the axle core that swing arm is rotated, and further purpose provides a kind of axle core that makes thermal source swing and can control its switch.

The utility model is realized in the following manner: a kind of axle core of thermal source overhead baking oven, comprise core body, and described core body is column, and its outer wall is provided with the guiding grooved ring that be arranged in parallel, spacing grooved ring and triggers groove.The axle core is plugged on an end of swing arm, and swings centered by the axle core, realizes that thermal source moves; The guiding grooved ring is set and cooperates with guiding bulge loop in the swing arm, realize the swing arm smooth rotation, spacing grooved ring plays the effect that the restriction swing arm excessively swings, and cooperate corresponding travel switch to play the effect of control of heat source switch by triggering groove, both made things convenient for the user to pick and place food, can also make the thermal source autoshutdown that moves apart working position, guarantee the use safety of thermal source.

As preferably, described core body outer wall is provided with the deep-slotted chip breaker bar, is provided with some hole clippings that are equally spaced in the described deep-slotted chip breaker bar.Hole clipping in the deep-slotted chip breaker bar and the locating dowel coupling holding and the location that are installed in the fork when locating dowel is plugged in the hole clipping, is guaranteed the thermal source location and are prevented that it from arbitrarily rocking, and effectively prevent from rocking the phenomenon that causes the user to scald because of thermal source; The hole clipping of a plurality of equidistant arrangements is set, is conducive to thermal source and realizes that horizontal hunting has the level location, guarantees user's safety.

As preferably, the guiding grooved ring is two, and on the parallel outer wall that is distributed in described core body.Article two, the guiding grooved ring splits on core body, and is both simple in structure, guarantees that also swing arm steadily swings on the axle core.

As preferably, be provided with a projection contour with its both sides cell wall in the vallecular cavity of described spacing grooved ring.The axle core swings by projection restriction swing arm, with the amplitude of fluctuation restriction of thermal source within the specific limits, reduces its required safe wobble area, eliminates safe hidden trouble.

As preferably, hole clipping is three, and is evenly distributed in the described deep-slotted chip breaker bar, and two hole clippings are separately positioned on two ends of deep-slotted chip breaker bar.Three hole clippings are simple in structure, and contained and be positioned at deep-slotted chip breaker bar each stations both sides and the middle part.

As preferably, described spacing grooved ring, triggering groove and deep-slotted chip breaker bar are all between two guiding grooved rings, from the two ends of axle core the swing arm restriction is located, guarantee that spacing grooved ring, triggering groove and deep-slotted chip breaker bar and corresponding component closely cooperate, realize thermal source automatic switch and steadily swing.

As preferably, described triggering groove position and the hole clipping location matches that is positioned at deep-slotted chip breaker bar middle part, its bottom is plane, and forms the cavity that uprises of the thin thick middle in two ends with the outer wall of core body.Trigger groove and travel switch coupling, by the swing arm of rotating so that trigger groove and travel switch interaction, when travel switch moves to the thicker zone of cavity of triggering the groove middle part, triggering part on the travel switch is because having the adequate space full extension and being triggered, so that thermal source normal operation, when travel switch moves to other positions, trigger part and be in non-triggering state because of compressed, thermal source is in closed condition, realizes that by this structure thermal source swing position is associated with himself switch.

As preferably, core body is hollow structure, and its inside has circular cylindrical cavity.The core body of hollow is lightweight, and saves material.

As preferably, described core body bottom is provided with one section cross section and is polygonal connecting portion.The axle core is connected on the polygon elevating lever of a coupling by the polygon connecting portion of bottom, both prevented from producing relative rotation between elevating lever and axle core, and so that the axle core lost efficacy to the restriction swing effect of swing arm, also so that elevating lever firmly is connected with the axle core, guarantee the stable grill top that is suspended at of thermal source.

The beneficial effects of the utility model: by researching and developing axle core a kind of and the swing arm coupling, can make swing arm in the purpose that realizes that thermal source steadily moves on grill, the relative position between axle core, swing arm is associated with the switch of thermal source; The structures such as spacing grooved ring, guiding grooved ring, buckle and triggering groove are set at the axle core, and cooperates with the swing arm of coupling, realize thermal source steadily swing and switch, both improved the convenience of operator when using, prevent effectively that also the higher thermal source of temperature from rocking, and guarantees to use safety.
